 Many of the very people who say they are shocked, shocked by Biden, showing were exactly the people that were covering for him. Ed Kransterman reacting to a video of Joe Biden tripping up the stairs in October 23. Once again, people are pretending to be frightened over the fact that Joe Biden stumbled. I literally stumbled going up the stairs at least twice a week. I even fell down my spiral staircase a couple of weeks ago. I'm 41. Work out daily and actually use the stair stepper. Should I be concerned?
